I have some files that I have bought and downloaded with iTunes (and removed DRM) and added to my plex library. Some does not play on the AppleTV4 but they play nice on the iPhone (both using the plex clients).
What could be the issue? To high bitrate? The screen just flickers black a couple of times and then returns to the movie info page.
Here is the media info from one of the movies that won't play:
